“…Sclerophyllous forests and scrubland of Mediterranean vegetation dominated by Olea europaea , Buxus sempervirens , Arbutus unedo and Laurus nobilis often appear not only along the coastline of the Euxine region but also in low elevational belts of inner Anatolia (Quézel et al., 1980; Yurdakulol et al., 1992, 2002; Kılınç & Karaer, 1995; Özen & Kılınç, 1995; Korkmaz et al., 2008, 2011; Karaer et al., 2010).

QuestionsWhat are the main vegetation types of forest and shrubland vegetation in central and eastern Euxine Turkey and SW Georgia? What are the main environmental factors affecting their diversity? What is their syntaxonomic position? Can we integrate them into the European vegetation classification system?LocationCentral and eastern Euxine Turkey and SW Georgia.MethodsWe collected 3104 vegetation plots of forest and shrubland vegetation in the study region and performed Two‐Way Indicator Species Analysis (TWINSPAN) classification. We described vegetation types based on the classification results, expert knowledge and information from literature sources. We defined diagnostic species and prepared distribution maps for each vegetation type. To determine the most significant environmental variables on floristic differentiation, we used canonical correspondence analysis. Detrended correspondence analysis with passive projection of most significant environmental variables was run to interpret the environmental variation of vegetation types.ResultsThe studied vegetation was divided into 29 vegetation types related to seven main vegetation groups: relict Mediterranean forests and shrubland (mainly along the coastline, beside some inland localities), lowland to submontane forests, central Euxine mountain forests, eastern Euxine (Colchic) mountain forests, subeuxine forests, azonal riparian forests and subalpine and alpine shrubland. Elevation is the most important factor causing the differentiation in vegetation. It is followed by longitude and latitude. Among climatic variables, temperature seasonality, annual precipitation and precipitation of the wettest quarter are the most significant factors for vegetation differentiation. These factors correlate with the reduction of maritime climate and geomorphological features.ConclusionsVegetation types mostly correspond to the syntaxa accepted in the EuroVegChecklist. However, some of them do not appear in the EuroVegChecklist since they appear only beyond Europe. We described three syntaxa as new: Abietion equi‐trojani, Querco cerridis‐Carpinion orientalis and Piceo orientalis‐Fagenion orientalis. The study revealed high vegetation diversity of the region that should be taken into consideration in ecosystem management and used as a reference in restoration and mitigation of the effects of global changes.

résorption foliaire de l'azote et du phosphore dans une forêt non perturbée et dans une forêt plantée de Pinus pinaster ait. dans le nord de la turquie. -La résorption foliaire est étroitement liée à la sénescence et à la conservation des nutriments et protège la plante dans sa dépendance des apports du sol. Dans la présente étude, ont été étudiées dans le nord-est de la Turquie la dynamique foliaire de l'azote (N) et du phosphore (P), l'efficacité (RE) et la profitabilité (RP) de la résorption foliaire de quelques plantes décidues existant dans une forêt non perturbée et dans une autre plantée en Pinus pinaster Ait. En forêt non perturbée, on n'a pas observé de différences entre les espèces pour ce qui concerne l'efficacité et la profitabilité alors qu'en forêt plantée en P. pinaster des différences statistiquement significatives ont été notées entre les espèces pour ce qui concerne la NRE, la NRP et la CRE. La CRE est apparue plus élevée que chez les angiospermes et graminoïdes ligneux sempervirents présents dans la zone d'étude. La NRE était plus forte en forêt non perturbée qu'en forêt plantée en P. pinaster. Dans les deux forêts la résorption foliaire de l'azote et du phosphore était biochimiquement complète. Il a été trouvé que la limitation en phosphore se produisait dans les plantes décidues des deux forêts au niveau des rapports N/P durant la sénescence foliaire. De même, le rapport C/N s'est avéré élevé durant la sénescence. En forêt plantée en P. pinaster le rapport N/P et la NRE (tant en masse qu'en surface) sont apparus plus faibles qu'en forêt non perturbée.SUmmARY. -Foliar resorption is closely associated with leaf senescence and conservation of nutrients, and protects the plant dependence on soil supply. In this study, leaf nitrogen (N) and phosphorus (P) dynamics, leaf resorption efficiency (RE) and resorption proficiency (RP) in some deciduous plants occurring in an undisturbed forest and a Pinus pinaster Ait. planted forest were investigated in northeastern Turkey. There were no significant differences among species with respect to foliar resorption efficiency and proficiency in undisturbed forest, whilst statistically significant differences were found among species regarding NRE, NRP and CRE in P. pinaster planted forest. CRE was found to be higher than for evergreen woody angiosperms and graminoids present in the study area. NRE was higher in undisturbed forest than in P. pinaster planted forest. In both forests foliar nitrogen and phosphorus resorption were biochemically complete. It was found that phosphorus limitation occurred in deciduous plants in both forests with respect to N/P ratios during leaf senescence. Similarly, C/N ratio was found to be high during senescence. In P. pinaster planted forest N/P ratio and NRE (both mass-and area-based) were found to be low as compared to undisturbed forest.Forests and tree plantations are increasingly considered for their central role as providers of habitat and regulators of global biogeochemical, temperature and water cycles.

“…The Alnus glutinosa subsp. barbata forests in the Colchic Region were classified as Alnion barbatae under Rhododendron -Fagetalia, which is the characteristic order of the Euro-Siberian zonal deciduous forests (Quézel et al, 1980;Quézel and Barbero, 1992;Akman, 1995;Korkmaz et al, 2008). However, Alnion barbatae forests are more riverine and ravine forests rather than being floodplain forests, but 14 diagnostic species were identified for Alnion barbatae (Akman, 1995) and only two of them, Circaea lutetiana and Frangula dodonei subsp.…”

In this study, the phytosociological structure of floodplain forests in the Euxine region of Turkey was examined from a large-scale perspective. For this goal, all of the published relevés were analyzed using the numerical classification and ordination techniques, which are widely used in phytosociological studies all over the world. In summary, a syntaxonomical scheme for floodplain forests with 11 communities (five associations and one alliance were newly identified) was suggested as follows: Fraxino angustifoliae -Ulmetum laevis Slavić 1952 allerietosum petiolatae Kavgacı et al. subass. nov. hoc loco; Fraxino angustifoliae -Ulmetum laevis Slavić 1952 junglandetosum regiae Kavgacı et al. 2011; Leucojo aestivi -Fraxinetum angustifoliae Glavač 1959 alnetosum glutinosae Glavač 1959; Smilaco excelsae -Fraxinetum angustifoliae Pavlov et Dimitrov 2002 prunellotosum vulgaris Pavlov et Dimitrov 2002; Apocyno veneti -Fraxinetum angustifoliae (Özen 2010) Kavgacı et al. ass. nov. hoc loco; Euphorbio strictae -Fraxinetum angustifoliae (Aydogdu 1988) Kavgacı et al. ass. nov. hoc loco (Alno -Quercion, Populetalia alba, Salici purpureae -Populetea nigrae); Aro hygrophyli -Fraxinetum angustifoliae (Kutbay et al. 1998) Kavgacı et al. ass. nova hoc loco; Pterocaryo pterocarpae -Alnetum barbatae Quézel et al. 1992; Platanthero chloranthae -Fraxinetum oxycarpae Korkmaz et al. 2012; Sambuco ebuli -Alnetum barbatae (Korkmaz et al. 2012) Kavgacı et al. ass. nov. hoc loco (Periploco graecae -Fraxinion angustifoliae Kavgacı et al. all. nova hoc loco, Populetalia alba, Salici purpureae -Populetea nigrae); and Geranio robertiani -Carpinetum betuli Kavgacı et al. 2011 (Carpino betuli -Fagion orientalis, Rhododendro pontici -Fagetalia orientalis, Querco -Fagatea).
